Invasive Speciesbittersweet nightshade

Solanum dulcamara
FOUND by Gorilla
ID Confirmed
Quality checked by White Tiger
Peer reviewed by Penguin
Field Notes
We found between 1-4 branches of the woody nightshade growing on a chain link fence in a group with some other plants. The berries on the plant were green and red in color, while one berry was more of an orange color. The nightshade seemed to be healthy but not yet encroaching on the other plant's space. The plant produced no audible noise, and had an unpleasant smell. We are surprised by what we found, as there were not as many berries as we expected

Supporting Evidence
Photo of my evidence.
The woody/bittersweet nightshade is reminiscent of the images of woody / bittersweet nightshade, as the berries are similar in shape and color, orange-red and green. This proves that it can't be deadly nightshade because deadly nightshade has black berries.

Our second piece of evidence is that there were arrow-shaped leaves with some purple in the leaves. In the packet we got it showed that wood/bittersweet nightshade leaves should be arrow-shaped and should have some purple in it.

Our third and final piece of evidence is that there were 2-10 berries on the stalks. When we looked at the packet it told us that there are supposed to be 2-20 berries per stalk.

Great work, Gorilla!

You did find solanum dulcamara. I am particularly impressed with your close observation of the leaf shape and color and how you ruled out deadly nightshade-- excellent observation skills! I'm interested in your note about how the solanum dulcamara does not seem to be encroaching on other plants yet. Do you think that this invasive is spreading rapidly? Has it been observed around your school grounds in the past?

Keep observing and stay curious!
